Specicaton forming part of Letters Patent No. 173,193, dated February 8, 1876; application filed December 18, 1875.

To all whom it may concern:

Be itknown that I, GEORGE F. UNDERHILL,

of Brockport, in the county of Monroe and` State otNewv York, have invented a newand.

Vuseful Improvement in Reapers and Harvesters 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had tothe accompanyirlg drawings, forming a part of this specication, in whichv Figure l represents a plan view of the finger bar attached to lthe platform, and having a finger or knife-guardsecured to it; and Fig. 2 represents a vertical cross-'section of the finger-bar and platform, showing the knife-guard above referred to in side eleration.

Similar letters of reference in the accom- Y panying drawings denote the same parts.

The object of this invention is to improve the mode of attaching the knifeguards or iugers ot' reapers and harvesters, and other similar agricultural machines, to the platform. or

Y other support; and to this end the invention consists in forming the connection between the fingers and their support by means of a T-shaped bar of metal, substantially as I will to Winona is fastened by horizontal. bons- D, .while one of its head-flanges ts closely up against the under edge of said platform, to which it is secured by similar vertical. bolts D1, and its remaining head-flan ge supports the lingers or guards U, which are bolted or riveted to it by vertical bolts D2.

ness, and gives it a double bearing-surface toward the platform and a convenient shoulder or flange for the guards. The bolts DDI, running through the front beam of the platform, l

both vertically and horizontally, hold the parts securely together and prevent the-beam from splitting or cracking longitudinally. The T-bar also'strengthens the platform-beam.

It is obvious that this mode of attaching i horizontal projecting arms or bars to the edge of any support like that shown at'B may be f employed to advantage in many other machines and structures besides those above re-A ferred to, as lit affords tivo stout Hanges 4through which to bolt it to the support, and

one through which to bolt the projecting arms to it. I regard all such arms as the equivalents of the 4parts C, and all' such. supports as the equivalents of the pants B, hereinabove shown and described; and

I claim as my invention? .The combination of the series of projecting fingers C with ythe support B, and with the inverted T-bar A, embracing said support, substantially as and for the purposes set forth.
